Power converters offer a high capability to efficiently manage electrical energy flows. Until few years ago, their primary use was in supplying motors in industrial applications and in electric traction systems. Nowadays, in addition to those fields they are employed in a very wide range of low, medium and high power applications including residential applications, renewable energy systems, dis...

Power efficiency is critical for electrical stimulators. Battery life of wearable stimulators and wireless power transmission in implanted systems are common limiting factors. Boost DC/DC converters are typically needed to increase the supply voltage of the output stage. Traditionally, boost DC/DC converters are used with fast control to regulate the supply voltage of the output. However, since...

Abstract Digital-to-analog converters are crucial building blocks for telecommunication applications. For this kind of applications, the traditional static performance requirements do not apply. The dynamic performance is of the greatest importance. This paper discusses the aspects of the performance of CMOS digital-to-analog converters and models the influence of non-idealities of circuit comp...

DC-DC converters have been applied to industrial applications widely during the past few decades. With rapid development of technology, negative output (N/O) dc-dc converters play an important role in the industrial fields, such as regenerative braking system (RBS) of DC motors for hybrid electric vehicles, signal generator and data transmission interface, neutral point clamping power electroni...

This paper describes a classification of paralleling schemes for dc–dc converters from a circuit theoretic viewpoint. The purpose is to provide a systematic classification of the types of parallel converters that can clearly identify all possible structures and control configurations, allowing simple and direct comparison of the characteristics and limitations of different paralleling schemes. ...

Diodeclamped three-level converters using direct torque control (DTC)...

High-speed and high-resolution analog-to-digital converters (ADC) are critical devices for space electronic systems. Analog Devices’s bipolar technology 12-bit A/D converter, AD574A, was proven to withstand up to 100 krad(Si) [1], but excessive power consumption limits its applications in many new high-speed and low-power system designs. Several other commercial 12-bit successive approximation ...

Introduction Instrumentation, waveform generation, data acquisition, feedback control systems and other application areas are beginning to utilize 16-bit data converters. More specifically, 16bit digital-to-analog converters (DACs) have seen increasing use. New components (see the sidebar “Components for 16-Bit Digital-to-Analog Conversion” on page 31) have made 16-bit DACs a practical design a...

Based on an algorithm derived from the New Chinese Remainder Theorem I, we present three new residue-to-binary converters for the residue number system (2 1 2 2 + 1) designed using 2 -bit or -bit adders with improvements on speed, area, or dynamic range compared with various previous converters. The 2 -bit adder based converter is faster and requires about half the hardware required by previous...
